Phenylphosphine is a clear, colorless liquid. Foul odor.
Использование
suzuki reaction
Общее описание
Clear colorless liquid.
Реакции воздуха и воды
Pyrophoric in air. Insoluble in water. Slowly generates flammable or noxious gases in contact with water.
Профиль реактивности
Phenyl phosphine is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.
Угроза здоровью
Phenylphosphine is a respiratory and skin irritant; multiple exposures in
rodents causes hematologic changes and testicular degeneration in males.
Пожароопасность
Flash point data are not available for Phenyl phosphine, but Phenyl phosphine is probably combustible.
Профиль безопасности
Poison by inhalation. Igmtes spontaneously in air. When heated to decomposition it emits toxic fumes of POx. See also PHOSPHINE.
Возможный контакт
Polyphosphinate is used as an intermediate or a chemical reagent. Polyphosphinate compounds are used as catalysts and antioxidants disproportionate, when heated to give phosphonic acid derivatives plus PF.
Перевозки
UN2845 Pyrophoric liquids, organic, n.o.s Hazard Class: 4.2, Labels: 4.2-Spontaneously combustible material. Technical Name Required. Note: this chemical is also a strong reducing agent.
Несовместимости
A strong reducing agent. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Water reactive; spontaneously combustible in high concentrations in moist air. Potential exposure to gaseous phenylphosphine and phosphorus oxides when heated above 200C. Organophosphates are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrideds and active metals. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
